Increase the property value of your home whilst savings on bills and carbon emissions with 100mm Knauf Earthwool DriTherm 32 Cavity Wall Insulation Slabs; an effective thermal solution, perfect for insulating masonry cavity external walls. 

These 100mm Earthwool semi-rigid glass mineral wool slabs are designed as a full fill cavity solution and boast an impressive A1 Euroclass classification. Being BBA certified, the slabs eliminate the need for cavity barriers with non-combustible full fill insulation, minimising the risk of fire spreading through a cavity. 

The 32 relates to the product's thermal conductivity value of 0.032 W/mK whilst the 'Dri' refers to the slab's water repellent additive, in conjunction with Knauf's unique ECOSE technology. 

Knauf DriTherm 32 100mm cavity insulation slabs are soft to the touch and provide excellent protection for the lifetime of the building. They are cut at 455mm wide in line with the positioning of standard wall ties, producing a closed joint with the adjacent slabs.

DriTherm Cavity Slab 32 Applications

Knauf DriTherm 32 is a glass mineral wool slab purposed for installation in external masonry cavity walls where a full fill insulation solution is required. The slabs are considered to be an effective thermal insulation solution for buildings up to 12m high and in multi-storey applications up to 25m high. 

The slabs knit together with both leaves of an external wall to eliminate air gaps and subsequent heat loss; DriTherm achieves this by fully filling the cavity and knitting together at joints. Despite its cotton soft composition, Dritherm boasts a firmness that ensures it stays put, wherever you position it. 

The slabs are 1200mm x 455mm, and are specifically designed to be compatible with standard vertical wall tie spacings without the need for retaining discs. Their sizing gives a closed joint with adjacent slabs, eliminating air gaps.

100mm DriTherm 32 Cavity Slabs come in a pack quantity of 6, giving a total pack coverage of 3.28m2.

Knauf DriTherm 32 Storage & Handling

As glass mineral wool is quite lightweight, the packs are a doddle to handle and move around. However, when it comes to moving pallets, a forklift should be used to prevent injury. Alternatively, the pallet can be split into packs which can then be moved individually.

Slabs are supplied in polythene shrink wrap for short-term protection. We advise that you store them indoors. As we know that's not always possible, our rule of thumb when it comes to storing outdoors is to keep the slabs above ground. Simply, pop them on a level surface and under a protective cover.
